COMPOSITE TILE ROOFING.

SPECIFICATION forming part of Letters Patent No. 226,983, dated April27, 1880.

Application filed December 3, 1879.

To all whom it may concern:

Be it known that I, WILLIAM DALE, of the city, county, and State of NewYork, have invented certain new and useful Improvements in CompositeTile Roofing, of which the fol lowing is a specification.

This invention relates to an improvement in that class of compositeroofing composed of tiles formed by filling a series of dish-shapedcast-iron plates with a suitable composition concrete applied in aplastic state and setting said tiles in a suitable supporting frame.These plates may or may not be provided with illuminating-openingscovered by glass panes or lenses held in place by the concrete; but asthis improvement relates only to forming a water-proof joint between thetiles it is equally applicable whether said tiles have illuminating-windows or not.

In the accompanying drawings I have represented my improvement asapplied to a roof provided with illuminating-windows.

Figure l is a plan view of a portion of two adjacent sectional tileswith a portion of their surrounding and supporting frame, the upper partof said figure showing the glass lenses and concrete inserted, while thelower part shows only the naked cast-iron plate. Fig. 2 represents across-section in line a0 m, Fig. 1.

A is the tile-plate; A, aportion of the supporting-frame; B, theilluminating-apertures; B, the glass panes or lenses, and (J theconcrete filling.

The tile-plates are cast with ribs a and a, crossing each other at rightangles, so as to I form a separate cell for each glass lens. Theseflanges of their adjacent sides, as shown in Fig. 2, and are screweddown to a cross-bar of said frame, as shown at A Fig. 2.

The concrete and glasses may be inserted either before or after settingthe tiles in the frame.

I form a waterproof joint between the adacent tiles by filling the spacebetween them with oakum or other suitable calking material, or ironborings and a solution of salamoniac, so as to form a rustjoint, or byinserting oakum at the bottom and iron borings and sal-ammoniac at thetop; or said tile-plates may be placed in close contact with each other,and nothing inserted between the flanges. In either case I cover saidjoint with a hood, D, in the form of an inverted gutter, made ofsheet-copper or other sheet metal with projecting flanges d on eachside, which are screwed down upon lugs 61, cast upon the tileplates.This cover, being made of flexible sheet metal, will expand and contractto adjust itself to any expansion or contraction of the cast-irontile-plates, and thus secure aperfectly waterproof joint whether anycalking material is inserted between the tiles or not.

I/Vhat I claim as my invention is 1. The pan-shaped cast-iron tilesfilled with concrete, and having projecting flanges adapted to be cappedby a sheet-metal hood, substantially as set forth.

2. In a roof composed of a series of panshaped cast-iron tiles filledwith concrete, as

described, with projecting flanges at their adjacent edges, the hood D,made of flexible sheet metal, covering the joint between the tiles,substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of .the subscribing witnesses.
